Determine the domain of the following graph:
Answer and explanation:
The domain would be [-9,3]. A closed circle lets you know if you will have to put parenthesis or a bracket when writing the domain. You can use every number between -9 and 3, including -9 and 3.
The domain of the given graph is -9 ≤ x ≤ 3.
What is domain ?The domain of a function f is the set of all values of x for which f(x) is defined and real.
Now from the given graph it is seen that the graph runs from -9 to 3 on x-axis.
and it is known that the domain of the graph is the set of all possible values of x.
Hence the required domain the given graph is written as,
-9 ≤ x ≤ 3
Thus, the domain of the given graph is -9 ≤ x ≤ 3.

simplify using i 3+2i/6+5i
Find the quotient using polynomial long division:
1. (50y^3+10y^2-35y-7)divided by(5y-4)
2. (8m^4-4m^2+m+4)divided by(2m+1)
(1) [tex]50y^3=5y\cdot 10y^2[/tex], and
[tex]10y^2\cdot(5y-4)=50y^3-40y^2[/tex]
Subtract this from [tex]50y^3+10y^2-35y-7[/tex] to get a remainder of
[tex](50y^3+10y^2-35y-7)-(50y^3-40y^2)=50y^2-35y-7[/tex]
What we've done here is show that
[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+\dfrac{50y^2-35y-7}{5y-4}[/tex]
We can keep going as long as the degree of the remainder's numerator is at least the same as the degree of its denominator.
Next, [tex]50y^2=5y\cdot 10y[/tex], and
[tex]10y\cdot(5y-4)=50y^2-40y[/tex]
Subtract this from the previous remainder to get a new remainder of
[tex](50y^2-35y-7)-(50y^2-40y)=5y-7[/tex]
which means
[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+10y+\dfrac{5y-7}{5y-4}[/tex]
Finally, [tex]5y=5y\cdot1[/tex], and
[tex]1\cdot(5y-4)=5y-4[/tex]
Subtract this from the previous remainder to get
[tex](5y-7)-(5y-4)=-3[/tex]
So we end up with
[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=\boxed{10y^2+10y+1}-\dfrac3{5y-4}[/tex]
(the quotient is the expression in the box)
(2) Using the same process as before:
[tex]8m^4=2m\cdot4m^3[/tex]
[tex]4m^3\cdot(2m+1)=8m^4+4m^3[/tex]
[tex](8m^4-4m^2+m+4)-(8m^4+4m^3)=-4m^3-4m^2+m+4[/tex]
[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-\dfrac{4m^3+4m^2+m+4}{2m+1}[/tex]
[tex]-4m^3=2m\cdot(-2m^2)[/tex]
[tex]-2m^2\cdot(2m+1)=-4m^3-2m^2[/tex]
[tex](-4m^3-4m^2+m+4)-(-4m^3-2m^2)=-2m^2+m+4[/tex]
[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-\dfrac{2m^2-m-4}{2m+1}[/tex]
[tex]-2m^2=2m\cdot(-m)[/tex]
[tex]-m\cdot(2m+1)=-2m^2-m[/tex]
[tex](-2m^2+m+4)-(-2m^2-m)=2m+4[/tex]
[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-m+\dfrac{2m+4}{2m+1}[/tex]
[tex]2m=2m\cdot1[/tex]
[tex]1\cdot(2m+1)=2m+1[/tex]
[tex](2m+4)-(2m+1)=3[/tex]
[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=\boxed{4m^3-2m^2-m+1}+\dfrac3{2m+1}[/tex]
A farmer has 180 yards of fencing material to make a rectangular
pen subdivided into 3 smaller pens. If the total length of the pens
is to be 60 yards, at most, how wide can the rectangle be?
Answer: 60 yd
Step-by-step explanation:
Here: subdivided into 3 smaller pens (2w + w + w) extra widths for separation purposes (3 smaller pens)
180 yards of fencing material
180yd = 2L + 4w
180dy = 2*60 + 4w
60dy = 4w
w = 15yd, how wide can the rectangle can be with L = 60yd

find the equation (in terms of x) of the line through the point (-4,3) and (3,-2)
Answer: y= -5/7 x + 1/7
Step-by-step explanation:
Answer:
[tex]y=-\frac{5}{7} x+\frac{1}{7}[/tex]
Step-by-step explanation:
Equation of a line: [tex]y = mx+b[/tex]
m is the slope, and b is the y-intercept.
m = [tex]\frac{rise}{run} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{-2-3}{3-(-4)} =-\frac{5}{7}[/tex]
Now, we have [tex]y=-\frac{5}{7} x+b[/tex]
We can insert one set of points in to solve for b.
We will use the first point (-4, 3):
[tex]3=-\frac{5}{7} (-4)+b[/tex]
[tex]\frac{5}{7}* \:4+b=3[/tex]
[tex]\frac{20}{7}+b=3[/tex]
[tex]b=\frac{1}{7}[/tex].
Equation:[tex]y=-\frac{5}{7} x+\frac{1}{7}[/tex]

solve for x:
2x+4=16
Answer:
6
Step-by-step explanation:
2x+4=16
2x=12
x=6
Answer: x = 6
Step-by-step explanation: To solve for x, we must first
isolate the term containing x, which in this problem is 2x.
Since 4 is being added to 2x, we subtract 4
from both sides of the equation to isolate the 2x.
On the left, the +4 and -4 cancels
out and on the right, 16 - 4 is 12.
So we have 2x = 12.
Then just divide both sides by 2 so x = 6.

The area of the star shaped surface of this block is 1.2m^2. The thickness of the block is 25cm. What is the volume of the block?
Answer:
volume = 0.30 m³
Step-by-step explanation:
GIVEN:
The area of the star shaped surface of this block is 1.2m^2.
The thickness of the block is 25cm.
FIND:
What is the volume of the block?
SOLUTION:
volume = area x length
where area = 1.2 m²; length = 0.25 m
plugin values into the formula:
volume = 1.2 m² x 0.25 m
= 0.30 m³
therefore, the volume of the star shaped block is 0.30 m³
